Quantifying Dispositional Fear as Threat Sensitivity: Development and Initial Validation of a Model-Based Scale...

Area of Science:

• Psychology
• Psychopathology Research
• Neuroscience

Background:

• The Research Domain Criteria (RDC) initiative shifts psychopathology research towards biobehavioral constructs.
• The RDC framework includes transdiagnostic constructs like 'acute threat,' relevant to fearfulness and stress reactivity.
• A structural model of fear/fearlessness questionnaires predicts physiological threat reactivity.

Purpose of the Study:

• To develop an efficient, item-based scale measuring the general factor of the fear/fearlessness model.
• To create a tool for studying dispositional threat sensitivity and its link to psychopathology.
• To provide a measure for the construct of 'acute threat' within the RDC framework.

Main Methods:

• Developed a 44-item self-report Trait Fear scale from a nonproprietary questionnaire in 1,307 students.
• Evaluated the scale's convergent and discriminant validity in a separate sample (n=213) of adults and students.
• Used the general factor of the fear/fearlessness model as a referent for scale development.

Main Results:

• The newly developed Trait Fear scale demonstrated strong performance in a criterion-validation sample.
• The scale effectively indexes variations in dispositional fearfulness.
• Findings suggest the scale's utility in assessing sensitivity to acute threat.

Conclusions:

• The Trait Fear scale is an effective measure for assessing dispositional fearfulness.
• This scale can be utilized in research on threat sensitivity and its relationship to psychopathology.
• The measure aligns with the Research Domain Criteria initiative's goals for transdiagnostic research.
